[PATCH 4.16 269/272] pinctrl: msm: Use dynamic GPIO numbering

[Greg Kroah-Hartman]

4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bjorn Andersson <bjorn.anders...@linaro.org>

[ Upstream commit a7aa75a2a7dba32594291a71c3704000a2fd7089 ]

The base of the TLMM gpiochip should not be statically defined as 0, fix
this to not artificially restrict the existence of multiple pinctrl-msm
devices.
